n Application October 26, 1 9o1aimks. (online- 5) The present inventionrelates to `roofing material and has particular .relation to stripshinglescomposed of a felt base impregnated and covered with asphalticmaterial. f

According tothe invention each shingle strip, comprising a body'portio'nwith av plurality of tabs along its butt edge,may be made of constantthickness along any liner' from its bottom redge to its top edge, thatis, from the butt edge to the opposite edge, but of varying thicknessIfrom* one side edge to the opposite side' edge, being of maximumthickness at the central-portionsof the adjacent tabs.

When laid upon a roof or other surfaca'the thick portions of one stripwill nest with the thin portions 'of the strip of sub-,jacent andsuper-k jacent courses of shingle strips, with the result thata largeportion of the thick, heavily vcoated parts of each shingle stripwill beexposed, while the thin, relatively lightly coated partsfof each stripvwill becovered byr shingles of adjacent courses, thereby affording theprotection and long wearing qualities fof any heavily coated roofingmaterial with a substantiallyminimum quantity ofy material and at lowcost. f

Another adv'antagetobe o of construction is that thek exposed tabs,being of increased thickness, throw ydeeper shadow lines on the roof andthus present a more pleasing appearance than do thel ordinary typeshingles of uniform thickness; land at the same time, due Ato thenesting of .the` thick and thin portions of super imposed shingles, asubstan- .tially'flat roof covering is provided. Further-K more, sinceeach tab of the shingle strips -isyre-` tabs, and tapering to minimumthickness between ses', serialN. sottisey n 1 lower edges I2 and I3 withthe recessesr I4` in the upper edges'yin vertical alignment with tabsI5-1pon vthe lower edges.v The body is of substantiallyfuniformthickness along lany vertical L line from bottom orbuttedg'ev I3 to theupper edge -'-I2, buty varisrin thickness from one "side edge IB to theOpposite side edge Il, being of maximum thickness ,in vertical bands I8which extend from thecentralpo'rtions of recesses I4 to the central edgeportions of tabs'l 5, and being of minimum thickness in vertical bandsI9 at the sidev edges 4of the strip and in vertical alignment withrecesses 2l -in the lower-edge I3 between tabs I5. The strippreferablyjtapers in'thickness iniyerticalbands 22 between adjacentbandsI8 and I9. The .strip shinglesare preferably formed as follows:` webv ofrooiingffeltfis impregnated and then heavily coated with Aasphalt orsimilar bituminous?v materiali Then the ,coated webis 'scraped orrolled, yor both., to produce contiguous thick, tapered, and thinbands'lon'gitudinally of k the web, vcorresponding tobandsfwlii, 22'andI9 in brained by this type the finished shingles. Such bands maybeVproduced by passingthe heavily coated .webund'er a scraper, to removeexcess lceatihng material; and then between yrolls having aA contourcomple--l mentary to thecross vsection of the shingle shown in Fig. 2. iy

The variati "nein thickness mais tn' web may be produced by scrapingthecoating on the underinforced by a thickened portion or rib extendinglongitudinally thereof, any' tendency of` lthe `errposed tabs to curl orto blow up in strong winds, is

jects and advantages will l of the typical embodiment lof the inventionthat is shown in the accompanying drawing, wherein: Fig. 1 is a planview of a strip shingle unit; .Fig 2 is a transverse vertical sectionthrough the unit;

Fig, 3 is a fragmentary front elevational view sholwinlg forward edgesurfacesv of a pair of shingle units in nestedv relation; and, y

Fig. 4 is a plan view showing a plurality of shingle units of adjacentcourses as they would be laid upon a roof.

As shown in the draw ing each shingle strip may consist of a body havingserrated upper and neath side `ofjtheweb to a uniform thickness, andvarying thethicknessjof thev coating on the top; the top being thesidefthat receives the iinishing surfacing material and is kthe sideexposed to the weatherpwhen tne shingles are'laid, or the variation inthickness can be obtained by maintainingauniform lthickness in thetoplayer .of coating asphalt, and Avarying the thicknessof the coating onthe underneath side, or bjoth top and bottom coatings can bevar-ied inthickness, "In'practice, the last named rnethodhasfbeen rfound mostsatisfactory. In using. anyi of the three methods, I find it preferableto keep theweb of rco-iing'f'elt y uniform vin thickness.

Thereafter any suitable lsurfacing 23,' such, kfor i I example ascrushed slate, maybe applied. Such -material is either not appliedy tomarginal portions of the web, or is scraped therefrom after the l fsurfacing operation, so that the sideyedge por- V`T'he nished web ofrooflng mate tions 24 of the finished shingle strips win be free ofthesurfacing material. y

rial may then be cut transversely, along serrated lines, toproduceindividually the shingle strips with serrated upper and lower edges I2and I3.

In laying the shingle strips upon a roof or other surface, the side edgeportions 24 of adjacent strips of the same course are preferablyoverlapped, and strips of adjacent courses are staggered, as shown inFig. 4, so that the tabs I5 of one course are in substantial alignmentvertically with ythe recesses 2l of super-jacent and sub-jacent courses,resulting in a roof covering of hexagonal design when the tabs are ofthe form shown in the illustrated embodiment.

As shown in Fig. 3, the thick, thin and inclined portions of any oneshingle nest with and complement the thin, thick and inclined portions,respectively, o-f an adjacent shingle. As shown in Fig. 4 the portionsor bands I9 of each shingle strip, including the overlapping portions 24are covered by adjacent courses of shingle strips, While almost theentire area of each thick portion or band If8 is exposed.

While -the invention has -been illustrated and described with referenceto strip shingles, it will be yunderstood that it may be applied tosingle shingles also, such a shingle having, forfexample, only one tabIand marginalportions 24 on each side thereof.

The drawing shows onlyone design of shingle, but it is to be understoodthat the linvention lends itself to other designs known to the art, asfor example the hexagonal strip shingle, and also square tab stripshingle; in fact, -t can vbe applied 'to any strip or individualshingles that are 4laid inoverlapping courses, whereinzthe overlying-shingles are offset horizontally from the course below the distance ofone-half the-width of one tab. v

It willbe understood further that the embodiments-of 4the inventionillustrated and described herein are merely exemplary of `the inventiveprinciples involved, and that these principles may be otherwiseYembodied withoutdeparting from the spirit of the `invention lor .thescope of the appended claims.
